Is it possible to take LVM snapshots of single whole disk installation under following circumstances?
root@talon1 ~ # lvs

root xubuntu-vg -wi-ao---- 464.30g

Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
From this tutorial, it looks like I need a separate partition.
Is it also possible to create a small 15-16 GB partition on the fly and use that for snapshot?

No unless you add another disk to the volume group.

I had a thought never done it before but you could use a ram disk if you have enough ram

I did answer his question his question was is it possible under these conditions and it a no. He did not ask how go about resolving the issue. I added that he would need to add additional storage. If he changes the question, I'll change my answer. I added my comment about ram disk because I don't know if it would work.
